Immediate coupling between servo engine and worm gear is one of the crucial strengths of EP worm gearmotors, which combine DC engine technology with exceptional durability and wear resistance. Electric motor and gearbox are designed as you single, compact unit. Because of their reduced current attract, these gearmotors deliver more accurate control of working temperature and higher efficiency.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based upon this we can select a wide selection of standard customizations to meet the requirements of varied properties that are essential for each application.
If your application requires a gearbox with some special real estate such as small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, extended life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our product range with an increase of than 1000 different standard gearboxes is most likely a good begin to have the ability to deliver a product that stands out in your favor.
Compact gearboxes are high-quality gearboxes for standard drives. The electric engine is included with the gearbox into a single unit (the first equipment is on the electric motor shaft). Separate gearboxes for connection to conventional IEC motors can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they can not be purchased in our e-shop. Our experts will be pleased to help you make your selection. We will be happy to send out you documentation or design a suitable set directly, on ask for.

Ever-Power worm gearboxes have earned a popularity to be a business benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the industry. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low velocity gear ratio. Being basic and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively bigger) and its own body is generally quite long in the axial direction. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key elements for low backlash, efficiently running and highly dynamic drive systems.
Our high-performance gear models are built to withstand the toughest commercial applications.
The gear housings are machined on all sides and permit diverse installation positions and applications, making them much sought after in the industry. As a result our geared motors tend to be to be found as part of our customers own devices.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design backed simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling get in touch with under load.
The special tooth root style in combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be used for the same torque, and smaller gears with outstanding power density can also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play necessary for troublefree rolling contact to be substantially reduced and then the gear backlash to become minimized.
Double chamber shaft seals developed by Ever-Power are utilized as regular in parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular equipment technology meets the requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
